TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Jan. 241, 1911.

VTo all whom 'it may co'ac'em:

Be it known that I, WALTER E. BARNARD, a lcitizen of the United States,residing in Hartford, in the county of Hartford and State ofConnecticut, have invented certain new and useful Improvementsin Type-Writing Maehines,. of which the following is a specification.

This invention relatestov margin regulat-` ing means for typewritingmachines, and morey especially to the margin controlling vdevices on theso-called wide-carriage maehines.

- 'In writing machines of the Underwood type, ityis customary to providea rack having arms journaled on the gage-supporting rod extendingparallel with the rack, the latter also havin an arm for actuating theusual signal .an key-locking mechanisms when the rack is rocked. Torocksaid rack, one of'a pair Ofinargin gages sliding 'on thegage-supporting rod is provided with a f cam riding upon the rack, whichcam is pressed down when-engaged by a tappet on' the carriage, to turnwith the gage around The margin gages operate -to control the .widths ofthe right and left-hand margins of the sheet, in a well known manner.The inner arm of the' rack, however, being journaled onthe rod midway ofits ends and of the run of the carriage, limits the range of adjustmentofrthe gages lsliding on. .the rod, the left hand gage cooperating with,and being 'adjustableonly between the arms of, the rack, and the right,Ihand gage being limited in its adjustment toward the left by itsengagement 'with the inner arm of the rack. One reason for usingsuch ashort rack is that the rack mustv be level at all times, as sagging orspringing would disar-- operator greater control of the widths of' themargins, so that both gages may slid to one extreme or the other ofthe'run of-the carriage, while preservlng the advanta s of the presentconstruction. To eiiect this end in an eilicient manner, and to providea device easily applicable to existing machines,

both gages being adjustable between the arms. of the rack from, end toend of therange of movement of the carriage.

In the accompanying drawings, Figure 1 is a perspective view,illustrating my invention applied to an Underwood type of front strikewriting machine. Fig. 2 is a cross sectional view, showing'the manner ofsustaining lthe gage-supporting rod intermediate its ends, and showingthe right hand gage clearing the rack. LFig. 3 is' a detail plan view,showing the right hand gage and carriage stop, and the connectionbetween the stop-controlling lever and the leverfor releasing theletter-spacing rack. Fig. 4 is a plan view, showing the margin gagesadjustable to either extreme of movement of the carriage, parts beingomitted to better disclose the construction. Fig. 5 is a crosssectionalside elevation, showing the lettery spacing rack released through theoperation of the stop controlling lever. Fig. 6 is a similar viewshowing the parts in normal position.

The usual carriage l of said Underwood writing machine runs upon a rail21 ysuported at its ends in the standard 2 of a rame A. The carriage hasa roll 23 to runupon sfaid rail. Upon-she carriage is xedvtheusualtappet 3 to engage a signaloperating and key-locking cam 14 mountedupon a margin 4gage 5 having a handle 5 for convenience in adjusting themargin gage back and forth on a gage-supporting rod 6, to control thepoint in the letter-spacing travel of -the carriage at which the signalshall be operated and the keys locked,

to terminate the line of writing. The gagesupportingfrod is fixed at itsends in the standards 2 of the frame and lies parallel with the rail 2l.

The function of the tappet 3, as usual, is to press the cam 14 down andthereby rock forwardly the pendent lever 16, said arm having at itslower end a head 16. to engage bell 171. The head also carries a pin 17to engage a spring actuated arm 18 on a rock shaft 18", which carries alookin bar 18, normally idle, but swung forward yby 105 a cam 17 on ahammer 17 which rings a'4 the `lever 16 to lock .the keys 18c after thebell 17h has been sounded.

rlhe lever 16 issecured to a bar 8 parallel with and having arms 4journaled on the gage-supporting rod 6; but instead efemploying theusual short bar with an inner arm journaled midway of the rod and therenby limiting the adjustment 4of the margin gage 5, I extend said barclear across the machine and journal its arms` onv thel rody nearits'opposite ends, preferably beyond the range of movement of the`carriage 1.

The bar 8 and operating lever 16 may bereadily applied to the usualgage-supporting rod commonly employed in machines of the Underwoodtype', Without alteration of the other parts of the machine. p It willbe noticed thatI the bar is angular in cross-secg tion, to add `strengthand resist sagging or springing;l such bar reaching across themachine'without intermediate support. When the cam 1li is pressed downby the tappetf 3' rod. It will be noticed that by extendingthe rack bar8 clear across themachine, the arm 4 thereof, usually journaled on therod midway of its ends, is set over out of the way, so that the travel'of the gage 5 "is no longer limited thereby, andan ample range ofadjustment of the gage yis permitted.

To support the gage-rod 6 without limit'l ing the range vof adjustmentofy the gage,

said rod is rigidly supported about midway of its ends, as by a hanger 9depending from the cross-bar 10 of the frame 2, and secured at its lowerend to the rod. Preferably, the rod is recessed at 11 to form a socketfor' the lower end of the hanger, which may be fastened to thegage-supporting rod by a pin 9a. The sleeve 12 of the gage, sliding onthe rod, is sl-itted, as at 13, to permit the gage to clear the brace orstrut 9 when adjusting the gage from end to end of the rod., The rockingof the cam 14 to operate the signaling and key-locking mechanisms alsorocks the margin ga e 5' on the gage-supporting rod 6, and t eslit 13 ismade ofl suiiicient width to perniit such rocking movement when thehanger 9 isembraced by the gage.

To regulate the Width' of thewlefthand margin of the sheet, the carriageis ,equippedy with a stop 2,5 to engage a shoulder 2li provided upon amargin gage# .19 which is adjustable along the rail 21 to arrestthe ear;

,voi

riage'when returning to begin a new line. The margin gage 19 issupported jointly' upon the rail 21 and the rod. 6 by bearing sleeve 2Oand 26,' respectivel and hence the' rocking of the rack has no e ect onthe margin gage 19, vbecause of its double support on the stationary rodand rail. The sleeve 201m the rail 21 is slotted, as at 22, to permitthe wheel 23 on the carriage to 'run vpast the sleeve, as whenshifting-the carriage past the margin gage. The body of said margin'gage is well above the rack 8 soy as not to interfere therewith, and thesleeve 26 on the rod is slitted, as at 27, to permit theI gage 19 to beslid past the brace 9.V Hence there is nothing to obstruct theadjustment of the gage to any `position betweenthe left and right handportions of the rod 6 and rail 21, the range of adjustment of bothgages^being no longer obstructed by the inner arm of the rocking rack.By dropping the 'brace from the cross bar 10 instead of'projeetingitfrom the rail 21, the brace lies out of the plane Y of the4 bodyportions of the gages, which need onlybe arranged to clear the brace atits point of engagement` with the .red .6. Accordingly the rack 29usuallyformed'on the front side ofthe rail 21 to be engaged by a dog 28pivoted at 28a on the gage 19 is extended nearly to the end of the rail21. as shown. A linger piece 28b onthe dog enables the dog to bereleasedfrom its rack.

To permit the operator to write in the left hand margin, or in a columnlying be- '100 hind the right hand margin gage, the carriage stop 25 isusually mounted on a lever 30 pivoted at 31, to the carriage 1 andhaving a key 32, the depression of which rocks the lever to throw thestop to inoperative position, so that it will clear the shoulder 24 onthe return of the carriage to the beginning of ay line.' In'thus'returning the car- .riagepas't the gage, the operator may overrun thepoint in the margin at which he wished to stop the carriage, especiallyin machines having .wide carriages,`vvhich re-l quire the 'applicationlof greater force to i return them than do the usual short carriages. Insuch event, the carriage cannot be moved in'letter-spacing directionback to such point, (because of the engagement of the usualletter-spacing'rack 33 hinged to the carriage at'34, with theescapement-con trolled wheel 35), except bythe manipulation oftherack-releasing lever 36, or by operating the usual space bar, Awhichdelays the operator. v

To enable the operator to morel speedily locate the carriage at thedesired stoppingy point behind the margin gage, I provide a singleswitch for effecting the release of the letter-spacing rack 33simultaneously with the shifting of the stop -25 to inoperativeposition, thereby permitting the carriage to shlfting lrack-,releasinglever,"so that the latter lever may be operated to releasethe rack fromthe escapement, against the tension of a returning sprintf 39, Withoutoperating the stopever. Depression of the stopshifting lever, therefore,will' operate the releasing lever 36 controlling the letterspacing rack33, to release the carriage 1 from the escapement and throw the stop 25to ineffective position.

It will be understood that the invention i herein disclosed is notrestricted to wide o the opposlte en carriage machines. Variations maybe resorted to Within the scope of the invention,

and portions of the improvements may be used without others.

Having .thus described .my invention, 'I claim: y
